(54)	Variable steering angle mechanism for vehicle steering control apparatus

(57) A variable steering angle mechanism for a steering apparatus is comprised of a differential gear unit (10) which includes first through fourth bevel gears (12,14,16,17), an input shaft (11), an output shaft (13) and a differential gear casing (20). The output shaft (13) is aligned with the input shaft (11). The differential gear casing (20) supports the third and fourth bevel gears (16,17) meshed with the first and second bevel gears (12,14) and is rotatable on the axis of the input shaft (11). A motor rotates the differential gear casing around the axis of the input shaft (11) to vary a ratio between a rotation angle of the input shaft (11) and a rotation angle of the output shaft (13).
